wow what organics was in that lol
how old are they if they are established it should be fine are you sure it is non systemic which means the leaves dont take it to the roots ?
they look ok to me what you worried about them girls looking mighty fine ?
a little heat stressed and maybe slightly only slightly add a bit of nitrogen when the leaves go like that at the sides it means they are dry craving for water a heat stressed plant does this its a way they deal with it
i agree but in this case maybe not the spots would be more evenly spread over the whole leaf but saying that you did say you put them outside for a day its a good job you got it isolated from the other 2
it wont hurt to give it a spray anyway
they should have been potted up ages ago m8 they are potbound
the answer to your question is the question itself
if a plant is in its vegetative state i would say get any plant food that says for vegetables high in nitrogen
if a plant is in its flowering stage i would say get any plant...
you have leaf spot fungus my friend very hard to get rid of and there is nute burn you dont need to be adding nutes at this stage just plain tap water not osmosis water just tap water thats left stood for 24 hours it has nutriants in it even direct tap water is ok there is no evidance to suggest...
